This invention relates to resilient bumpers for cushioning the contact'of door edges with door casings and the connection and assembly of such bumpers to the door post ordoor casing.

curely locked therein by a partial rotation of the bumper in the socket.

Another Object of the invention is to provide a bumper and a socket ina door post of special construction adapted to cooperate for efficient tension and easy assembly.

The above being among the objects .of the present invention, the same consists in certain features of construction and combination of parts to be hereinafter described with reference to the accompanying drawing and then claimed, having the above and other objects inview.

In the accompanying drawing which illustrates suitable embodiments of the present invention and in which like numerals refer to like parts throughout the several views Figure 1 is a fragmentary perspective view, of a door post equipped with a bufier constructed in accordance with my invention. Fig. 2 is a fragmentary perspective view of the construction'of the door post shown in Fig. 1 with the buffer removed therefrom.

' Fig. 3 is a fragmentary perspective view of a door post having a bufler therein disposed in position, disclosing the first step in assembling the buffer to the door post.

Fig. 6 is a plan view of a buffer constructed in accordance with my'invention.

Fig. 7 is a sectional view of the buffer disclosed in' Fig. 6, taken substantially along line 7.7 of Fig. 6.

Fig. 8 is a sectional view of. the buffer disclosed in Fig.6, taken substantially along line 88 of Fig. 6. r 1 i I Heretofore bufiers in the door jamb have been secured therein by means of a screw or the like or a cover plate, or they were 1nserted-in the socket provided therefor by greatly compressing the bufi'er and forcing it into the socket and reliance placedin resiliency of the buffer to maintain it in place. When employing the present invention in connection with doors of motor vehicle bodies the door post 11 may be provided with a rabbeted edge portion 12, having surfaces 13 and 14, and a jamb'face portion 15. The edge of the door 'lOis provided with corresponding surfaces.

As shown in Fig. 2, the door post is provided with-a socket'16, open at the j amb face 15 and rabbet face 14, and which is defined by the cylindrical wall 17 and flat wall 22 of a metal stamping'which has lateral flanges secured to the rear face of the jamb face 15 by welding or otherwise. A'flange 18, formed i by the edges. of the jainb face'15 around the opening therein, extends inwardly around the edge of the socket at the jamb face 15.

The opening in the rabbet face 14 is sub-' stantially less in length than the diameter of the cylindrical backing piece 17-22. A buffer element 23 of any resilient material, but preferably a rubber block, is formed and secured in the socket 16, as hereinafter explained. The buffer 23 is formed. with an undercut flatted edge portion 25, arcuate edge portions 26 at each end of'the fiatted edge and a reduced arcuate edge portion-'27 opposite the fiatted edge 25. This reduced arcuate edge portion 27 may beprovided with a'flat edge face if desired. The maximum width of the block taken parallel to the flatted edge 25 is substantially equal to the diameter of the socket 1722 taken parallelto the rabbet face 14; i

-This block is provided with a circumferential groove 31 which follows the arc of the reduced arcuate edge portion 27 except 7 along the fiatted edge 25, through which it V 26 into the socket behind the flange 18, which the reduced arcuate edge 27 facing the edges 19. and 2-0 respectively of the opening as shown in Fig. 3. The block is then shoved into the socket in a straight line, withthe flange 18 entering the groove 31 along'the' flatted edge 25, until one of the arcuate ends 26 strikes. the wall 17 opposite the opening in the rabbet face 14, and is then given a quarter turn to rotate the outwardly, extendingend follows the groove 31, and tobring the reduced arcuate portion 27 into its projecting position in the rabbet as shown in Figul. The block is thus locked in thesocket against movement perpendicular to the j amb face 15 by the'fiange 18. engaging the grooves 81 along the arcuate edge portions 26, and from movement perpendicular to rabbet face14 by the bearing of the arcuate edges 26 against the converging walls 17 adjacent the opening, as the maximum width of the block taken parallel to the fiatted edge 25 is substantially equal to the diameter of the socket 1722 taken parallel to the rabbet face 14.

The lip 20 serves as a limiting stop to such turning movement of the buffer by engaging the adjacent shoulder 28 of the latter, and also conceals the shoulder. If desired, the other edge 19, instead of edge 20, may be provided with the lip and in this event, the buffer would be positioned vice versa of that described above, in inserting it. Preferably in actual practicethe lip will be located at the upper edge, because it will conceal the upper shoulder 28 of the buffer which otherwise would be more readily seen by observers. However, if desired slight lips may be provided at both edges 19 and 20 of the opening in therabbet face 14 which will engage the shoulders 28 on the edge of theblock at each end of the reduced arcuate portion 27, to assist in retaining it in the socket.

The face 24 of the block projects beyond the jamb face 15 and its edges 30 cover the edges of the socket opening, which provides a neat appearance. These overlapping edges 30 of the face 24 are not essential to the operation and efficiency of the bufler, however, and may be dispensed with if desired. f 4

To remove the buffer from the socket it is rotated untilit again assumes the position From the foregoing description it is at parent that I have provided abuffer that. is easily assembled and-removed relative'to the door post and one that will not be dislodged spirit or substance of thebroad invention,
